BACKGROUND 1. Field

The present disclosure relates to shipping containers, and more particularly to shipping containers with features to allow for custom sizing, opening or unboxing experience for the end user, and the like.

2. Description of Related Art

Products that up until recently were almost exclusively purchased in a physical retail setting are increasingly available to consumers through ecommerce venders that ship the products directly to the consumer. For shipping purposes there is a concomitant shift from shipping in bulk to shipping products on an individual basis. Traditionally, ecommerce products are packed in standard boxes with standard packing such as bubble wrap as needed.

The conventional techniques have been considered satisfactory for their intended purpose. However, there is an ever present need for improved packaging, e.g. for shipping ecommerce products and the like. This disclosure provides a solution for this need.

SUMMARY

A container includes a blank including a plurality of panels foldably connected to one another and erected about an interior space, and a plurality of top flaps foldably connected to the plurality of panels to enclose a top end of the interior space, and a plurality of bottom flaps wherein each of the bottom flaps is foldably connected to a corresponding panel of plurality of panels to enclose a bottom end of the interior space. The blank includes a line of weakness pattern configured to allow a user to break the top flaps from a closed configuration enclosing the interior space to an open configuration allowing access to the interior space.

The plurality of panels can include a front panel, a first side panel, a back panel opposed to the front panel, and a second side panel opposed to the first side panel.

The top flaps, the first side panel, and the second side panel can include perforations of the line of weakness pattern. The perforations in the top flaps can define a top opener feature configured for a user to initiate breaking the top flaps. The perforations in the first and second side panels can follow respective arcuate paths. Each of the front and back panels can include a respective hinge line defined therein for hinging the blank into the open configuration. Each hinge line can extend into each of the first and second side panels.

The top flaps can include a back top flap foldably connected to the back panel, a front top flap foldably connected to the front panel, a first side top flap foldably connected to the first side panel, and a second side top flap foldably connected to the second side panel. The top opener feature can be aligned with the edge notches of the first and second side top flaps. The perforations across each respective one of the first and second side top flaps can divide each of the first and second side top flaps into a front portion and a back portion, wherein the front portions are adhered to the front top flap, and wherein the back portions are adhered to the back top flap.

In another aspect, it is also contemplated that the top flaps and the front panel can include perforations of the line of weakness pattern. The perforation in the front panel can define an opening tab configured for a user to initiate breaking the line of weakness pattern. The top flaps can include a back top flap foldably connected to the back panel, a front top flap foldably connected to the front panel, a first side top flap foldably connected to the first side panel, and a second side top flap foldably connected to the second side panel, wherein the line of weakness pattern includes perforations in the front top flap, the first side top flap, and the second side top flap. The perforation in the first side top flap can divide the first side top flap into a breakaway portion adhered to the top back flap and a non-breakaway portion adhered to a non-breakaway portion of the front top flap. The perforation in the second side top flap can divide the second side top flap into a breakaway portion adhered to the top back flap and a non-breakaway portion adhered to a non-breakaway portion of the front top flap. A breakaway portion of the front top flap can be adhered to the breakaway portions of the first and second side top flaps.

103, 105, 107, 109 are foldably connected to a

corresponding panel

102, 104, 106, 108 to enclose the interior space 110 (indicated in FIG. 4). Each of the

bottom flaps

103, 105, 107, 109 are separated from each other, and each is only attached to each

corresponding panel

102, 104, 106, 108. The plurality of

panels

102, 104, 106, 108 include a front panel 102 foldably connected to a first side panel 104 along a fold line 122, a back panel 106 opposed to the front panel 102 and foldably connected to the first side panel 104 along a fold line 124, and a second side panel 108 opposed to the first side panel 104 foldably connected to the back panel 106 along a fold line 126. An adhesive flap 128 is foldably connected to the second side panel 108 along a fold line 130 opposite the fold line 126.

The

top flaps

112, 114, 116, 118 include a front top flap 112 foldably connected to the front panel 102 along a fold line 132, a back top flap 116 foldably connected to the back panel 106 along a fold line 136, a first side top flap 114 foldably connected to the first side panel 104 along a fold line 134, and a second side top flap 118 foldably connected to the second side panel 108 along a fold line 138 (where

fold lines

132, 134, 136, 138 are optionally collinear).

With reference again to FIG. 1, the blank 100 includes a line of weakness pattern. The

top flaps

112, 114, 116, 118, the first side panel 104, and the second side panel 108 include

perforations

160, 162, 164, 166, 168, 170 of the line of weakness pattern. The

perforations

160, 162 in the first and

second side panels

104, 108 follow respective arcuate paths. The

perforations

168, 170 in the

top flaps

112, 116 define a top opener feature 174 configured for a user to initiate breaking the

top flaps

112, 114, 116, 118.

With reference again to FIG. 1, the

top flaps

112, 116 include corresponding crushed

regions

113, 115. The crushed

regions

113, 115 have a smaller thickness than the rest of the

top flaps

112, 116. This allows the top portion 120 of container 101 to have a smoother closure when folded and closed.

The line of weakness pattern includes

respective perforations

164, 166 across each respective one of the first and second side top flaps 114, 118. The

perforations

164, 166 across each respective one of the first and second side top flaps 114, 118 can each connect to an edge notch 176 in the respective one of the first and second side top flaps 114, 118. The top opener feature 174 is aligned with the edge notches 176 when the container 101 is formed, as shown in FIG. 2. The

perforations

164, 166 divide each of the first and second side top flaps 114, 118 into a front portion 178 and a back portion 180. It is also conceived that

perforations

164, 166 can be fully or partially broken, or cut instead of being perforations. The front portions 178 are ultimately adhered to the front top flap 112, e.g., using adhesive lines 182, and the back portions 180 are adhered to the back top flap 116, e.g. using the adhesive lines 182, to form the container 101 shown in FIG. 2.

Each of the front and

back panels

102, 106 includes a respective hinge line 184 defined therein for hinging the blank 100 into the open configuration shown in FIG. 3. Each hinge line 184 extends into each of the first and

second side panels

104, 108 as oblique fold lines 186 which facilitate opening the container 101 into the open configuration shown in FIG. 3.

With reference now to FIG. 4, a method includes packaging a plurality of product items into respective containers 101. For each container 101, packaging includes (as indicated in stages 1 and 2 of FIG. 4) forming a blank 100 as described above around a mandrel 188 to surround the interior space 110 as shown in FIGS. 2-3. The adhesive flap 128 can be adhered to the front panel 102 using adhesive line 190 (labeled in FIG. 1). The top flaps 112, 116 can be adhered outside of the

top flaps

114, 118 using the adhesive lines 182 (labeled in FIG. 1). Folding each of the bottom flaps 103, 105, 107, 109 across corresponding

panel fold line

123, 125, 127,131 in order to enclose the container 101 from an end opposite the top end 120.

Product can be placed inside the interior space 110, e.g. after the mandrel 188 is removed in stage 3 of in FIG. 4, so that the product is packaged inside the interior space 110 at stage 6 of FIG. 4. For each respective container 101, the method can include cutting the plurality of

panels

102, 104, 106, 108 (e.g. at stage 3 of FIG. 4) to a custom length to fit a custom shipment of product (e.g., as in a fulfillment center in ecommerce) before closing the container, wherein the custom length varies from container 101 to container 101.

With reference now to FIG. 2, and end user can open the container 101 by breaking the line of weakness pattern described above and hinging the

top flaps

112, 114, 116, 118 into the open configuration shown in FIG. 3. The end user can break the opening feature 174 in the top flaps, gripping the opening feature 174 (e.g. by manually gripping the edge notches 176, labeled in FIG. 1, and pulling apart as indicated by the large outward facing arrows in FIG. 3) to break the

top flaps

114, 118 along

perforation lines

164 and 166. This allows hinging the

top flaps

112, 114, 116, 118 and upper portions of the

panels

102, 104, 106, 108 into the open configuration along the hinge lines 184 as shown in FIG. 4. The end user can then remove a product item or items from the interior space 110.

With reference now to FIG. 5, another embodiment of a blank 200 is shown with

panels

202, 204, 206, 208 and

top flaps

212, 214, 216, 218, and adhesive flap 228 foldably connected together much as described above with respect to FIG. 1. There is a line of weakness defined the

top flaps

212, 214, 216, 218 and the front panel 202 that include

perforations

260, 264, 266. The perforation 260 in the front panel 202 are configured for a user to initiate breaking the line of weakness pattern. The line of weakness pattern includes perforation 260 in the front top flap 212 and front panel 202, and

respective perforations

264, 266 in the first side top flap 214 and the second side top flap 218. The perforation 264 in the first side top flap 214 divides the first side top flap 214 into a breakaway portion 278 adhered to the top back flap 216 with adhesive 282 (and adhered to a breakaway portion 298 of the front top flap 212 with adhesive 283) and a non-breakaway portion 280 adhered to a non-breakaway portion 294 of the front top flap 212 with adhesive 285. The perforation 266 in the second side top flap 218 divides the second side top flap 218 into a breakaway portion 278 adhered to the top back flap 216 with adhesive 282 (and adhered to the breakaway portion 298 the front top flap 212 with adhesive 283) and a non-breakaway portion 280 adhered to a non-breakaway portion 296 of the front top flap 212. The container 201 shown in FIG. 6 can be formed using a similar process to that described above with respect to FIG. 4.

With continued reference to FIG. 6, the end user can open the container 201 by breaking the line of weakness pattern. This includes breaking the opening tab 272 in the front panel 202, breaking

perforations
